Systematic Evaluation of the Upper Airway in a Sample Population

Abstract

This is the first study in which a systematic evaluation of the UA was followed by a sleep study in a population-based sample. In a sample of the general population that had not previously been screened for OSAS, having an abnormal nasal structure was found to be a risk factor for OSAS, in conjunction with other well-established clinical and demographic factors, such as male gender, increased age, increased neck circumference, and body mass index.
